Mistake granted, however Pre/Post turbo the concept is the same. My wife understands the concept because she was a diving instructor and scientist. She is actually fascinated by the concept of cooling the air to increase compression. She told me about having to cool down the scuba tanks in water when they filled them with air. She thought that if we sprayed cold water on the intercooler we could probably lower the temp even more, I told her they already invented that.
